Abstract

We present a successfully treated female infant suffering from congenital tracheal stenosis combined with hypoplasia of right lung, left pulmonary artery sling and bridging bronchus. A 9-month-old female was referred to our hospital with aggravation of stridor caused by upper respiratory infections. Chest-enhanced CT scan revealed congenital tracheal stenosis combined with right lung hypoplasia. Four days after admission, she developed sudden respiratory failure immediately after continuous weeping, subsequently requiring intubation and mechanical ventilation. As her respiratory condition did not improve, we performed slide tracheoplasty and tracheopexy at day 7 after admission. We hypothesized that the acute respiratory failure might be related to tracheal flexing caused by a mechanism similar to postpneumonectomy syndrome, where the trachea was translocated anterior to the aortic arch with slide tracheoplasty. Furthermore, tracheopexy with pericardium roll was added to alleviate postoperative tracheomalasia. The postoperative course was noneventful: she extubated at postoperative day 12, and discharged three weeks after operation.
